摘　　要：在目标跟踪系统中,传感器量测因通信延迟无序地到达融合中心,产生无序量测融合问题。针对此问题,将H∞滤波作为基础滤波算法,提出了一种可处理单步或多步延迟无序量测的新算法。新算法借鉴有序滤波思想,利用等价量测来代替无序量测发生时刻后的量测序列,然后从该时刻起利用无序量测和等价量测进行有序更新。仿真实验表明,新算法相比于传统算法有更高的滤波精度,尤其在系统模型误差较大时仍有良好的滤波效果。In target tracking systems,sensor measurements may arrive at the fusion center out ofsequence because of the communication delays,which results in the Out-of-Sequence Measurement(OOSM)problem.Aiming at the above problem,taking H肄filtering as the basis filtering algorithm,anew algorithm can deal with both1-step-lag OOSM and multi-step-lag OOSM is proposed.The newalgorithm deal with OOSM by combing the framework of in-sequence filtering method the equivalentmeasurement is used to replace the measurement after the moment when the OOSM measured,andthen updates from that moment with the OOSM and the equivalent measurement.Theoretical andsimulations show that,compared to the traditional algorithm,the new algorithm has a higher filteringaccuracy,especially when the system model error is large.
